Title: Improvements relating to railway signalling apparatus
IPC: B61L5/18
Filed: 1927-02-01
Abstract: 289,563. Peter, L. H., and Westing- house Brake & Saxby Signal Co., Ltd. Feb. 1, 1927. Electromagnetic switches.-In a railway signalling apparatus employing alternating current for feeding a signal lamp, a rectifying device, preferably of the metallic oxide type as described in Specification 257,305, [Class 37, Electricity, Measuring &c.], is associated with the signal lamp circuit to provide unidirectional current for a relay operating an indication device. The signal lamp 9 is energized by a transformer 11, the primary 12 of which is connected in series with the energizing winding 7, Fig. 1, of a relay controlling a locking segment 18 and the circuit of an indication lamp 17. The winding 7 is shunted by a rectifier 8 so that when the signal lamp 9 is operative, the winding 7 is traversed by alternate half cycles of the current in the transformer primary 12, and the armature of the relay is maintained in a position completing the circuit of the lamp 17 and holding the locking segment in the required position. If, however, the signal lamp 9 becomes inoperative, the increase in impedance of the primary 12 reduces the current in the relay 7 to an extent allowing the armature to be released to provide the required indications. In a modified arrangement, Fig. 3, both half waves of the supply current are caused to traverse the winding 20 of the relay by using a pair of rectifiers 8<a>, 8b in conjunction with a resistance 19, 21 connected as shown. In a further modification, the relay winding is connected in series with a single rectifier and bridged across a portion of a resistance in the primary circuit of the transformer.

Title: Improvements relating to fire-control apparatus
Inventor: NELSON HUMPHREY GORDON
IPC: G01C21/18
Filed: 1951-02-09
Abstract: 700,315. Fire-control apparatus. FERRANTI, Ltd. Feb. 11, 1952 [Feb. 9, 1951], No. 3155/51. Class 92(2) A fire-control apparatus comprises a frame 10 mounted as shown so that it rotates about elevating and training axes, and carrying, in gimbal frames, a line-of-sight gyro 18 and a vertical gyro 19. The axis of the gyro 18 is maintained by a predictor, on the line-of-sight and pick-ups 20, 21, associated with the gyro are connected to motors 13, 16, to maintain the axis of the frame 10 in alignment with the axis of the gyro. The axis of gyro 19 always remains vertical. On a shaft 51 extending from the frame 10 is rotatably mounted a toothed disc 52, and on this disc is mounted a curved rail 54 which  is centred on the centre point 17 of frame 10 and which is bisected lengthwise by a plane containing the line-of-sight axis. A carriage 55 is movable along the rail under the action of a motor 56 controlled from the predictor, the carriage carrying one part 58 of a pick-up whose other part 59 is carried by a bow 60 associated with the gun. This bow is pivotally carried by a bracket 61 which pivots about the training axis, and the part 59 is so associated with motors 62 and 63 for driving the bow and bracket respectively that the gun is trained and elevated to accord with the training and elevation of the imaginary line joining the part 58 with point 17. To effect this result it is necessary that the plane of the rail 54 is maintained in the imaginary plane containing the line of sight to the target and the line of flight to the target. This is achieved by a motor 65 mounted on a plate 64 and geared to the disc 52, the motor being controlled by the predictor. The plate 64 is mounted to rotate on the spindle 51 and is given rotational movements by a stabilizing motor 67 controlled by a pick-up 74, 75 associated with the gyro 19. Thus, any deviation of the frame 10 relative to the vertical results in rotation of the motor 67 by the pick-up 74, 75, the plate 64 then carrying the motor 65 round with it to rotate the disc 52 and rail 54 through the appropriate angle. A slot may be provided in place of the rail.

Title: Process for the dyeing of finished goods, especially textiles
IPC: D06B5/24
Filed: 1960-02-01
Abstract: <PICT:0890633/IV (c)/1> A process for the dyeing of finished goods, especially textiles, on forms is characterized in that, after each dyeing operation, one portion of the used dye liquor is discharged and the other portion is used again for the next dyeing operation, fresh liquor of constant composition being added in an amount corresponding to the amount of used liquor discharged.  As shown the process may be effected in apparatus comprising a storage container 1 connected to a dosing vessel 5 by means of a tubular conduit 2 incorporating a filter 3 and an electrically operated valve 4.  A tubular conduit 7 also leads to the dosing vessel from a collection vessel 6 in which the already used liquor is stored, this conduit including a filter 8 and electrically operated valve 9. Associated with the dosing vessel is a double electrode water level control 10, the long electrode 11 of which controls the amount of fresh liquor from the reservoir and the short electrode 12 of which controls the amount of the already used liquor from vessel 6.  Liquor from the dosing vessel 5 is discharged through the conduit 121 via a magnetically controlled valve 13 into a pressure vessel 14.  The pressure vessel contains forms 15 carrying finished goods to be dyed, a pump 16, spray 17, steam outlet valve 18 and electrically controlled inlet for steam 19. Dye liquor circulates through pump 16, spray 17, over the finished goods and collects in the base of the pressure vessel to be acted upon by the pump again.  To fill vessel 14, valve 4 is opened and fresh dye liquor from container 1 flows into the dosing vessel 5 up to the level controlled by electrode 11. Valve 4 is automatically closed and valve 9 opened.  Used liquor flows from vessel 6 into vessel 5 up to the level controlled by electrode 12. Thereupon valve 13 is opened and valve 9 shut automatically, causing the dye liquor to flow into the pressure vessel. Circulation causes homeneneous mixing of the used and fresh dye liquors as the finished goods are dyed, after which pump 16 is stopped, electrically operated valve 20 is opened and the used dye liquor is forced by pressure from within vessel 14 through conduit 21 to vessel 6.  Subsequently valve 20 is closed and residual steam pressure released through valve 18.  In a modification (not shown) only a part of the dye liquor is discharged by use of an electrically operated valve, that part of the liquor situated below the valve being re-used in the next dyeing cycle.

Abstract: 610,555. Typewriting, &c., machines. SMITH & SON, Ltd., W.H., FLAWN, P. A., and LANEGAN, F. E. Feb. 4, 1947, No. 3725. [Class 100(iv)] In or for an imprinting machine, such as a tabulating or calculating machine, of the kind in which a continuous length of stationery is automatically fed by electrically driven means past a writing position in throws of two different lengths, the shorter throw corresponding to line spacings and the longer throw to form heading spacings on the stationery, controlling means is provided for stopping the operation of the stationery feeding means at the end of the longer throw, comprising a twopart member arranged for rotation as a unit in synchronism with the feeding means one part being driven for rotation in synchronism, and the drive between the two parts being releasable to permit circumferential adjustment, and means operable at the end of the longer throw by an abutment surface on the other part of the rotatable member to break the circuit controlling the driving means for the feed, without disconnecting the drive between the two parts of the rotatable member. The stationery is fed by means of a pair of pinwheels engaging marginal perforations therein and carried on a shaft 5, Fig. 3, driven from the normal stationery feeding mechanism of the machine in short and long throws through a gear train, not shown. On the shaft 5 is mounted a gearwheel 9, which drives a gear-wheel 12 through an intermediate gear 10 mounted on a quadrant 11. The gear 12 is attached by bolts 15 passing through holes therein to a disc 14, the bolts passing through slots 16 in the disc, and the gear being mounted on a shaft 13. The disc 14 carries two studs 17 which engage a spring leaf 18 mounted on an insulating block 19 and operate the plunger 20 of a micro-switch to break the circuit controlling the feed mechanism. In order that the studs will contact the leaf at the end of the longer throw, the disc 14 can be adjusted relatively to the gear 12 within the limits of the slots 16.

Title: Decoding systems for colour television receiver
IPC: H04N11/16
Filed: 1972-01-26
Abstract: 1351403 Colour television SONY CORP 26 Jan 1972 [29 Jan 1971 (2)] 3747/72 Heading H4F In a PAL demodulation system the chrominance signal, Fig. 3, is passed to demodulators 2 and 3, Fig. 4, via a direct path including switched diode 12 or a delayed path including one line period delay 10 and switched diode 13. The operation of the diode switching the associated control means 11, 14-20, is such that alternate lines are fed twice in succession to the demodulators, i.e. a line, e.g. 7th is fed via diode 12 to the demodulators and is then fed again in the next line interval via the delay 10 and diode 13. The demodulators are thus fed with signals having a constant carrier phase, i.e. the "phase alternating line" is compensated for. The colour burst signals B have + on - signs (phases) depending as the phase of the chrominances signal carrier. The frame or burst blanking period B B  moves its position in the line structure in a four frame cycle, Fig. 3, and the described embodiments select the earliest occurring first B + burst, i.e. that following the third burst blanking period. The burst signals Fig. 5A, are separated out by filter 4 and after amplification in AGC amplifier 18, 19 and detection by diode 20 are passed to an AND circuit 16. A monostable circuit 14 produces a signal S1, Fig. 5B, from the vertical sync. pulse Vs, lasting 5H and ending just before the selected burst is to occur. Signal S 1 in turn produces a gate signal S2 from generator 15 which selects and gates through AND circuit 16, the selected burst. After detection, said burst sets the state of bi-stable control circuit 11 such that the diodes switching circuit 9 is always controlled to produce a modified chrominance signal of the correct constant carrier phase. In the embodiment of Fig. 7 (not shown) a quartz crystal tuned coil, tuned circuit produces a continuous oscillation from the burst signals having a phase midway between the alternate chrominance signal phases. This exhibits exponention decay between bursts with the largest increase in amplitude occurring at the first burst signal after the blanking period. This increase is detected and used to produce a special pulse which is gated through AND circuit 17 as described above.
